How to stay a up-to-date researcher in ML/RL community?
There are some wonderful resources for keeping up to date in the ML community. Here are just a handful that a coworker showed me:


Deep Learning Monitor: this site contains hot and new papers along with tweets that are popularized by the community! You can even checkout RL papers specifically here  
arxiv-sanity: this site updates with popular and new papers that make it onto Arxiv
papers with code: this site is wonderful because not only does it link to papers, but it links to their implementation for reproduction or assistance in your own personal projects. They even have a leaderboard and track state of the art (SoTA) on tons of different tasks  
DL_twitter loop: You can't forget twitter, given that most researchers use it; this is just a single nice group you may like
